Textile fabric defect detection model and training method and application thereof

The invention discloses a textile fabric defect detection model and a training method and application thereof. The training method includes the steps that sample textile fabric defect images are acquired, a data set is established, and the textile fabric defect detection model is established based on YOLOv2; dimensional clustering is used before the model is trained, when the model is trained, coordinate prediction, loss value calculation and counterpropagation are directly carried out, and current network weight parameters are obtained; network weight parameters of the textile fabric defect detection model are updated through the current network weight parameters, then multiple times of network weight calculation and update are carried out through a training set, optimal network weight parameters are obtained, and accordingly the trained textile fabric defect detection model is obtained; then textile fabric images are acquired in real time, the trained textile fabric defect detectionmodel is used for detecti
